Controlling the population of a country or society is very important as it will help control and manage a lot of things.
I think the countries that are controlling birth date are really doing well almost in all ramifications. In that way, if there leaders aren't corrupt, unemployment rate will reduce, the budget allocated will be enough.
Take for instance a family that has little amount of children like two or maximum of three, to cater for the needs of those children won't be hard compared to having a great number of children like eight, ten or a dozen. If they aren't too much the parent will be able to provide for the needs of children easily and also overseeing them to the point that the children will be independent to some extent.
In a place like Nigeria my country, where birth rate is not controlled, anyone can give birth to any number of children they ought to, a man can decide to marry as many wife as possible thereby giving birth to as many children as possible. Sometime ago I learnt about a man that got married to 86 wives and 138 children, although that's the man's choice but is it healthy for the society? I don't think so.
Overpopulation is one of the problems we're facing in Nigeria, a lot of people are just giving birth to children without thinking twice. You will see parent that aren't financial bouyant enough to cater for three children but gave birth to six to seven children, thereby in one way Increasing the poverty rate.
All this kinds of acts needs to be checked, the government should stop folding their arms but should act swiftly. They need to be involved in this matter else the employment rate, poverty rate, crime rate will keep increasing by the day because as it stands now, it seems the number of people that's available for a particular job are more than the job positions.
Every year, my country produce hundreds of thousands corp members, but still what's their achievement after service, most people start from scratch again, most will have to go back to learning a skill.
Moreover, the economy is not smiling at all at the moment, the cost of goods and services are getting high each and everyday, the price you hear or see today will be different from what you'll hear tomorrow, it's just too bad. So bringing innocent children to this kind of economy when you know you can't take care of them is not good enough. Even the rich do not give birth to many children, it's the poor people that's mostly involved in such act. Those days our fore father's use to give birth to many children mainly because of farm work, so they will see people that will assist them on the farm because most of them are farmers. That was the major work everyone is doing but today, that trend still continues even though the parent are not farmers, just giving birth to children without proper planning.
I strongly believe that regulating the number of children in a family will make things better, all our government need do is just put it into law and ensure that it's followed, with that, a lot of wrongs will be corrected.
